Calculate n(T)/n(1000K) for tungsten emitter at T=300K, 2000K and 3000K


Calculate $\mathrm{n}(\mathrm{T}) / \mathrm{n}(1000 \mathrm{~K})$ for tungsten emitter at $\mathrm{T}=300 \mathrm{~K}, 2000 \mathrm{~K}$ and $3000 \mathrm{~K}$ where $\mathrm{n}(\mathrm{T})$ represents the number of thermions emitted per second by the surface at temperature $T$. Work function of tungsten is $4.52 \mathrm{eV}$.
